Novartis receives positive CHMP opinion for Kesimpta®* (ofatumumab), a self-administered treatment for adult patients with relapsing multiple sclerosis
- Kesimpta is a targeted B-cell therapy that delivers superior efficacy with a similar safety and tolerability profile compared with teriflunomide, a first-line treatment in MS1
- CHMP opinion is based on two Phase III ASCLEPIOS studies that met the primary endpoints where Kesimpta showed a reduction of the annual relapses by over 50% versus teriflunomide and achieved more than 30% relative risk reduction of 3-month confirmed disability progression (CDP) 1
- In a post hoc analysis, nearly nine out of 10 patients treated with Kesimpta achieved no evidence of disease activity (NEDA-3) in their second year of treatment2
- If approved, Kesimpta will be the first and only self-administered, targeted B-cell therapy for patients with relapsing multiple sclerosis in Europe
Basel, January 29, 2021 — Novartis announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion and recommended granting marketing authorization of Kesimpta® (ofatumumab) for the treatment of relapsing forms of multiple sclerosis (RMS) in adults with active disease defined by clinical or imaging features. Kesimpta is a targeted, precisely dosed and delivered B-cell therapy that has shown superior efficacy with a similar safety profile compared with teriflunomide, a first-line treatment in MS1. Kesimpta has the potential to become a first-choice treatment option for patients with RMS that can be self-administered once-monthly at home via the Sensoready® autoinjector pen3.
“In MS, one of the main goals of treatment is to achieve no evidence of disease activity as early on and for as long as possible4,” said Dr. Xavier Montalban, Multiple Sclerosis Centre of Catalonia (Cemcat), Vall d'Hebron University Hospital. “Knowing that early initiation of high-efficacy treatments can improve long-term outcomes5, it’s exciting to see that Kesimpta has the potential to halt new disease activity and help people to preserve neurological function and slow down the worsening of disability2.”
The CHMP opinion is based on results from the Phase III ASCLEPIOS I and II studies, in which Kesimpta demonstrated superiority versus teriflunomide in significantly reducing the annualized relapse rate (ARR, primary endpoint), 3-month confirmed disability progression (CDP), and the number of gadolinium-enhancing (Gd+) T1 and new or enlarging T2 lesions1. Results from these two studies were published in the August 6, 2020 issue of The New England Journal of Medicine.
A separate post hoc analysis demonstrated that Kesimpta may halt new disease activity in RMS patients, with nearly nine out of 10 patients treated with Kesimpta achieving no evidence of disease activity (NEDA-3) in their second year of treatment2.
The CHMP recommended approval for Kesimpta with an indication for the treatment of adult patients with RMS with active disease defined by clinical or imaging features. The European Commission will review the CHMP recommendation and deliver its final decision in approximately two months.
In August 2020, the US Food and Drug Administration approved Kesimpta as an injection for subcutaneous use for the treatment of RMS, to include clinically isolated syndrome (CIS), relapsing-remitting disease, and active secondary progressive disease, in adults. On January 25, 2021, Kesimpta was approved in Canada for the treatment of relapsing remitting multiple sclerosis (RRMS).

About Kesimpta® (ofatumumab)
Kesimpta is a targeted, precisely dosed and delivered B-cell therapy that provides the flexibility of self-administration for adults with RMS. It is an anti-CD20 monoclonal antibody (mAb) self-administered by a once-monthly injection, delivered subcutaneously1,3. Initial doses of Kesimpta are given at Weeks 0, 1 and 2, with the first injection performed under the guidance of a healthcare professional. As shown in preclinical studies, Kesimpta is thought to work by binding to a distinct epitope on the CD20 molecule inducing potent B-cell lysis and depletion8. The selective mechanism of action and subcutaneous administration of Kesimpta allows precise delivery to the lymph nodes, where B-cell depletion in MS is needed, and preclinical studies have shown that it may preserve the B-cells in the spleen9. Once-monthly dosing of Kesimpta differs from other anti-CD20 therapies as it allows faster repletion of B-cells, offering more flexibility in MS management10. Ofatumumab was originally developed by Genmab and licensed to GlaxoSmithKline. Novartis obtained rights for ofatumumab from GlaxoSmithKline in all indications, including RMS, in December 201511.
About ASCLEPIOS I and II studies
The ASCLEPIOS I and II studies are twin, identical design, flexible duration (up to 30 months), double-blind, randomized, multi-center Phase III studies evaluating the safety and efficacy of Kesimpta 20 mg monthly subcutaneous injections versus teriflunomide 14 mg oral tablets taken once daily in adults with RMS. The ASCLEPIOS I and II studies enrolled 1,882 patients with MS, between the ages of 18 and 55 years, with an Expanded Disability Status Scale (EDSS) score between 0 and 5.51. The studies were conducted in over 350 sites in 37 countries12. Kesimpta demonstrated a significant reduction in ARR by 51% (0.11 vs 0.22) and 59% (0.10 vs 0.25) compared with teriflunomide (P<.001 in both studies) in ASCLEPIOS I and II, respectively (primary endpoint). Kesimpta also showed a relative risk reduction of 34.4% (P=.002) in 3-month CDP compared with teriflunomide, as defined in ASCLEPIOS1.
Kesimpta showed significant reduction of both Gd+ T1 lesions and new or enlarging T2 lesions. It significantly reduced the mean number of both Gd+ T1 lesions (98% and 94% relative reduction in ASCLEPIOS I and II, respectively, both P<.001) and new or enlarging T2 lesions (82% and 85% relative reduction in ASCLEPIOS I and II, respectively, both P<.001) vs teriflunomide1.
Kesimpta had a similar safety profile to teriflunomide, with the frequency of serious infections and malignancies also being similar across both treatment groups. Upper respiratory tract infection, headache, injection-related reactions and local injection site reactions were the most commonly observed adverse reactions with Kesimpta (incidence greater than 10%)1.
A separate post hoc analysis demonstrated that Kesimpta may halt new disease activity in RMS patients. It showed the odds of achieving NEDA-3 (no relapses, no MRI lesions, and no disability worsening combined) with ofatumumab versus teriflunomide were >3-fold higher at Months 0–12 (47.0% vs 24.5% of patients; P<.001) and >8-fold higher at Months 12–24 (87.8% vs 48.2% of patients; P<.001)2.
Overall Kesimpta, an antibody targeting CD20 positive B-cells, delivered superior efficacy and demonstrated a safety and tolerability profile with infection rates similar to teriflunomide1.
About APLIOS study
The APLIOS study is a 12-week, open-label, Phase II bioequivalence study to determine the onset of B-cell depletion with Kesimpta subcutaneous monthly injections and the bioequivalence of subcutaneous administration of Kesimpta via a prefilled syringe—as used in ASCLEPIOS I and II—and a Sensoready pen in patients with RMS. Patients were randomized according to injection device and site including the abdomen and thigh. B-cell depletion was measured nine times over 12 weeks and Gd+ lesion counts were assessed at baseline and at Weeks 4, 8 and 12. Regardless of injection device or site, Kesimpta 20 mg subcutaneous monthly injections resulted in rapid, close to complete and sustained B-cell depletion; the proportion of patients with B-cell concentrations of <10 cells/μL was >65% after the first injection by Day 7, 94% by Week 4 and sustained >95% at all following injections. Kesimpta treatment reduced the mean number of Gd+ lesions from baseline (1.5) to 0.8, 0.3 and 0.1 by Weeks 4, 8 and 12, respectively. The proportion of patients free from Gd+ lesions at the corresponding time points were 66.5%, 86.7% and 94.1%, respectively3.
The ASCLEPIOS and APLIOS studies form part of the AXIOS Program, the overarching ofatumumab clinical development program, which will expand the evidence of ofatumumab in MS.
About Multiple Sclerosis
Multiple sclerosis is a chronic inflammatory disease of the central nervous system characterized by myelin destruction and axonal damage in the brain, optic nerves and spinal cord13. MS, which affects approximately 2.8 million people worldwide14, can be characterized into four main types of MS: CIS, relapsing-remitting (RRMS), secondary progressive (SPMS) and primary progressive (PPMS)15. The various forms of MS can be distinguished based on whether a patient experiences relapses (clearly defined acute inflammatory attacks of worsening neurological function), and/or whether they experience progression of neurologic damage and disability from the onset of the disease13.
